The wax pattern is ideal for obtaining records, as it was injected directly over the cast, and therefore will fit (Figure 19). If the dentist desires, a post dam can be cut into the cast prior to injecting. The wax pattern is also familiar and comfortable for the patient and provides a reference to communicate to the laboratory, from which any and all changes are made predictably. The Celara wax pattern is handled just like a wax rim. Base plate wax can be added to it, or it can be marked and trimmed similar to a traditional rim.

Troubleshooting — Fabricating the Wax Pattern

•Avoid injecting too cool a temperature.

–This will result in a wavy wax pattern.

•Avoid injecting the wax too hot.

–This can result in excess shrinkage of the wax pattern.

•Avoid having the sprue hole too large.

–It will not make a seal in the inlet of the injector and the pattern may not fill with wax.

•Avoid having the inlet sprue hole too close to the ledge of the container.

–This will make it very difficult to place the container on the inlet of the wax injector.

•Avoid having the inlet sprue into the anterior teeth.

–The inlet sprue should enter the void above the anterior teeth in the anterior flange of the denture. The anterior teeth and midline must be accurately represented in the wax-pattern.

•Avoid injecting the alginate wet. Dry the alginate before injecting.

–The incisal edges of the anterior teeth will not be represented accurately if excessive moisture is in the alginate.

•Avoid pumping the wax injector too vigorously — Pump very slowly and easily.

–This can shoot the wax out the exit sprue, which will make a mess and possibly cause injury.

•Avoid removing the container from the inlet sprue of the container too quickly.

–Allow the wax to harden in the sprue before lifting the container off the inlet of the wax injector. This prevents the wax from running out and creating a void in the pattern. The resulting void will be in the distal of the pattern.

•Allow the wax pattern to adequately harden before removing it from the cast and trimming to prevent distortion of the wax pattern.
